Description
Technical field
The utility model relates to a kind of mechanical engineering vehicle, specifically is meant a kind of full size vehicle of following hoisting crane automatically that is loaded with track.
Technical background
Maximization is the development tendency of China's weight equipment manufacture and shipping industry, needing parts weight, the oad of processing all to have significantly increases, this just need mill construction have span big (generally above 40 meters), highly high, carry big characteristics and could satisfy manufacturing, processing technology requirement.The problem that this mill construction brings is that the composition error that shows on crane track of the factory building distortion that causes owing to reasons such as civil engineering sedimentations is bigger, much larger than the GB allowed band; Simultaneously, the side direction integral rigidity of large span crane system is relatively poor, and the nominal error in manufacturing, the installation process can cause that also cart produces deviation in the process of walking.Two kinds of deviations all can make hoisting crane wheel and track produce interference.
At present, the suitable way of the interference that solution hoisting crane body error causes is more, generally all is by adjusting the big vehicle speed in both sides the actual travel distance of both sides wheel to be consistent, but needs to guarantee that the deviation of orbital distance is in more among a small circle.The large span factory building since load-bearing greatly, highly high, make mill construction distortion meeting very big and very irregular, adopt present universal method track and wheel still can produce very serious interference.
The utility model content
The utility model has overcome above-mentioned the deficiencies in the prior art, and its purpose is to provide a kind of track to follow crane automatically.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of track is followed crane automatically, comprise crane wheel, drive motor, retarder, drg, master controller, PLC, frequency converter, track, detecting device, it is characterized in that: drive the one-sided cart actuating device of crane track respectively by two frequency converters, four jiaos of crane are equipped with eight cover detecting devices; Detecting device detects and is connected with PLC by signal transmssion line; PLC is connected with two frequency converters.
In the utility model, comprise the cart drive part of forming by crane wheel, drive motor, retarder, drg, by master controller, PLC (Programmable Logic Controller), two cart speed control parts that frequency converter is formed, and the test section of forming by track, detecting device (comprising detecting sensor and sensor adjustment device).Two frequency converters drive the one-sided cart drive part of crane track respectively, at hoisting crane four jiaos eight cover detecting devices are installed; Detecting device detects the gap of wheel and track and is converted to electric signal, and gather by PLC, PLC is according to the sensor signal state and in conjunction with the order of master controller control and regulate the output of two frequency converters, thereby the real-world operation speed that makes hoisting crane both sides cart drive part changes and changes the gap of wheel and track, realization lifting function is followed track and is changed and change automatically, constitutes track and follows crane automatically.
The utility model is compared the beneficial effect that has with background technology:
1) this track is followed automatically and is made big mechanism of car follow the variation of track automatically and change under the situation that crane can be out of shape at mill construction, the gauge deviation is bigger, realizes smooth running.Comformability and in-use performance have been improved.
2) this track is followed crane automatically and can be substituted conventional hoisting crane body deviation correcting device easily, improves the adaptive capacity to track when guaranteeing the apparatus body function.
3) it is simple in structure, easy for installation that this track is followed crane automatically.Can effectively avoid the interference of wheel and track, the stationary performance when having improved the cart operation; Reduce big mechanism of car running resistance, reduce the operation energy consumption of cart; Simultaneously, maintenance number of times, the difficulty of big mechanism of car and track be can reduce, maintenance, maintenance cost reduced.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Embodiment 1
According to Fig. 1, Fig. 2, Fig. 3, structure shown in Figure 4, the utility model comprises the cart drive part of being made up of crane wheel 1, drive motor 3, retarder 2, drg 4, by master controller 8, PLC7, two frequency converters 11,12, the cart speed control part of forming, and the test section of forming by track 5, detecting device 6; Two frequency converters 11,12 drive the one-sided cart drive part of crane track 18,19 respectively, at hoisting crane four jiaos eight cover detecting devices 6 are installed, and the gap that detecting device 6 detects wheels 1 and track 5 also is converted to electric signal; The electric signal of detecting device is gathered by PLC7, PLC7 is according to detecting device 6 signal conditions and in conjunction with the order of master controller 8 control and regulate the output of two frequency converters 11,12, thereby the real-world operation speed that makes hoisting crane both sides cart drive part 18,19 changes and changes the gap of wheel 1 and track 5, realization lifting function is followed track 5 and is changed and change automatically, constitutes the crane track following control system.
Above-described drive motor 3 is buncher.As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the working process of crane track following control system is: master controller sends operational order, PLC7 checking system state (states such as stop gear 13, trouble diagnosing mechanism 17) sends corresponding given order to frequency converter 11,12 by the control of having set/given mechanism 14 after satisfying condition of service, and frequency converter 11,12 moves drive part on request; PLC7 detects the signal condition and the signal value of eight cover detecting devices 6 in real time in the operational process, and force additional given to frequency converter 11,12 at any time according to track detection control mechanism 15 that configures and track detection computations mechanism 16, thereby the corresponding change of the output valve of frequency converter 11,12 meeting changes the real-world operation speed of drive part, the wheel 1 and the gap of track 5 are changed, thereby make the actual curve operation of drive part according to track 5.
What wherein part detecting device 6 detected is the gap width of hoisting crane wheel 1 and track 5, and what the detecting device 6 of part detected in addition is the clearance conditions of wheel 1 and track 5.Track detects the signal condition that control mechanism 15 reads relevant detection device 6, obtains the clearance conditions of hoisting crane wheel 1 and track 5, judges the drive part that needs adjusting in conjunction with the hoisting crane service direction; Track detection computations mechanism 16 reads the signal value of relevant detection device 6, obtains the gap width of hoisting crane wheel 1 and track 5, the annex given value that need regulate in conjunction with the real-world operation speed calculation of hoisting crane.
Routine possesses cart deviation-correcting function hoisting crane and is based on track 5 deviation in range values in GB regulation allowed band, thereby the actual travel distance unanimity that guarantees the both sides drive part satisfies operating needs.Adopt after this crane track following control system the hoisting crane drive part can be according to the operation of track 5 actual curves, not only can satisfy track 5 deviation in range values in GB regulation allowed band operating mode and also can satisfy track 5 deviation in range values and surpass GB regulation allowed band.The limit range of using interferes with track 5 as hoisting crane both sides wheel 1 outer rim or both sides wheel 1 inner edge simultaneously, and the limit range that wheel 1 adopts wide wheel rim design back to use will be followed the increase of wheel rim width and be increased.
